We currently have a Zenworks 17.3 zone setup on a Windows server. We want to switch over to the appliance version. I setup the appliance just fine. In the Server Configuration, I am choosing "Add new Primary Server". When it asks for the information for our current server, I type in everything correctly but I get the message "Unable to authenticate to primary server". I have tried FQDN and IP for the server address with no luck. I know the Server address, Username, and Password are correct. It is defaulting to port 443. Is that the correct port to use? Is there a log I can view to find out why it won't connect? I used the Terminal and File Explorer and I am able to ping the Primary Server. Is there any other commands to use?
